The check for official builds now only affects the case where a prebuilt
kernel was actually used, not the case where a device builds a kernel
from source as normal.
The check has also been turned around so that it only fails the build if
it's actually an official build, not an unofficial one.

* TARGET_FORCE_PREBUILT_KERNEL should be useful when you don't have ready kernel sources (OEM releasing broken sources or releasing them lately)
* It lets you use kernel sources for userspace generated headers (generated_kernel_headers) while keeping using prebuilt kernel
* Keep in mind that generated kernel headers may not align with the ABI of kernel you're including
* This commit also partially revert commit a836d79, where TARGET_KERNEL_SOURCE would have been unset if TARGET_PREBUILT_KERNEL was defined (we already check in kernel.mk if kernel sources are present anyway)

* GCC was deprecated awhile ago, the large majority
of devices should now be using this. Clang should
be opt out as opposed to opt in.
